ELLIS O. LONG, OF MANSFIELD, OHIO DUMPlNG-W-AGON- Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed July 14, 1904. Serial No. 216,584.

To nJ/Z whom it puny concern- I ing-wagons which are adapted to dump the contents of the wagon-box without the necessity of using a shovel or other device in removing the contents from the box.

The objects of my invention are, first, to afford facilities for dumping all of the contents of the wagon at one time or in case it is desired to do so to afford means of dumping a part of the contents only.

A further object of my invention is to provide a means for reducing the force or pressure of the load upon the slats when the operator is in the act of dumping the contents of the wagon-box.

Another object of my invention consists in the construction of a wagon-box having a series of crank-shafts journaled in suitable bearings or braces provided on the sides of the box, upon which shafts are mounted and securely attached a series of hinged folding plates adapted to overlap each other, and a draw-bar composed of a series of double links secured to the cranks of the shafts and means for imparting motion to all of the plates or slats simultaneously or separately at the option of the operator.

I attain these and other objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my invention, showing the operating mechanism with the slats or plates comprising the bottom of the box in open position. Fig. 2 is an end elevation. Fig. 3 is a side view of the double links, showing one of the links in closed position and the other link broken or in open position. Fig. 4 is a detailed top view of one link, showing its construction, and a side and end view of the locking-knuckle. Fig. 5 is a side view of the front end of the box, showing an auxiliary end hinged to the upper portion, with a resilient catch or spring secured to the end of the box and adapted to hold the auxiliary end at an incline with the body portion, as shown in dotted lines. Fig. 6 is a top view ofthe hinged folding slat or plate. Fig. 7 is a bottom view of Fig. 6, showing the method of hinging the plates to provide a means for folding them and also showing the coil-springs having their ends engaging the movable and stationary portions of the plate. Fig. 8 is an end view of the hinged plate or slat, showing it in folded position, and also the broken end of the crank-shaft.

Referring to the drawings, 1 indicates an ordinary wagon or box having its sides 2 flaring for the purpose of providing a means for increasing the capacity of the box. In constructing the box I prefer to securely attach a series of braces 3 at intervals along each side thereof, the braces having their lower ends 5 turned up to provide hooked bearings, the ends of the hooks extending above the level of the bottom of the box to close the bearings and prevent any danger of the shafts becoming disengaged therefrom. These braces are secured to the sides of the wagon-box in direct alinement with each other, and their number can be variedso as to provide for different sizes, widths, or dimensions of slats or plates, which will be described more particularly hereinafter. The upper ends 4 of the braces conform to the contour of the flaring sides of the box to strengthen the latter.

A series of crank-shafts 6 are journaled in the opposite hooked bearings 5 and extend transversely across the box, the upturned ends 7 of the crank-shafts being flattened and apertured, as at 8, for the reception of a pivot-pin or rivet 9. A draw-bar 10, composed of a series of double links 11, having suitable apertures in the ends thereof adapted to receive the ends of the rivets 9, is adapted to connect the upper ends of the crank-shafts. The links 11 between their points of connection with the crank-shafts are pivotally connected together by means of the rivets 13, the links being held in alinement by means of the locking-knuckle 12, consisting of a substantially U shaped member, the arms of which fit over and embrace the adjacent ends of the links at their pivotal point 13 to resist and prevent the breaking of the levers or links in a downward direction. The free end 14 of the series of links forming the drawbar is pivotally connected to the lever 15, which is an extension of that crank-shaft adjacent to the forward end of the box. One member 16 of the hinged folding plate is securely and rigidly fastened to the crank-shaft by the clamps 17 and is termed the stationary member. The remaining member 16? is connected to the member 16 by the hinges a and b, forming a complete plate or slat.

IIO

Two coil-springs 18 and 19 are securely attached to the bottom of the stationary member in such a manner as to leave ends 20 and 21 exerting a pressure against the bottom of the hinged member 16 for automatically returning and maintaining it on a plane and in alinement with the stationary member 16 preparatory to closing the bottom after the contents of the box have been .dumped. The complete plate comprising the members 16 and 16, is mounted upon each of the crankshafts, leaving a margin of the hinged or folding member of the plate overlapping the next succeeding stationary member 16 for supporting it when the plates are closed, forming an imperforate bottom for. the box. A space is left between the foremost plate and the front end of the box, the front plate having two resilient catches 22 attached to its forward edge and projecting therebeyond. An auxiliary end 23 is hinged to the upper portion of the end of the box' and is adapted to swing loosely therefrom, the auxiliary end being normally retained at an incline, as shown in dottedlines 23, Fig. 5, with the body portion by the flat tension-springs 2 1, riveted to the end of the box. The auxiliary end when the box-bottom is closed is supported by the brackets or catches 22. A bracket 23 is attached to the rear end of the box for the purpose of supporting the rear plate or slat when the bottom is closed. A notched segment 25 is secured to the-side of the box, with which segment the lever 15 is adapted to mesh for securely locking the bottom in closed position.

It will be noted that each complete slat or plate is mounted upon the crank-shaft a certain predetermined distance from the adjoining slat, so as to leave a margin of the movable member of each slat resting on and overlapping the stationary member of the next succeeding slat, which is securely attached to the crank-shafts for supporting the movable member and preventing it from dropping under the weight of the load. The cranks of the several shafts are in lateral alinement and disposed parallel with each other, their upper ends being connected together by means of the double-linked draw-bar, one end of which is secured to a lever, the draw-bar normally being horizontal, with the links in substantial alinement. hen movement is imparted to the lever, it is communicated to the draw-bar and crank-shafts, upon which the plates or slats are mounted, giving them an oscillating motion with the inclination of the plates or slats toward the front end of the box, whereby the stationary members 16 are positively rotated to the inclined position,(shown in Fig. 1,) thereby withdrawing their support to the movable members 16, which drop to the position shown in Fig. 1 under the weight of the load. hen force or pressure is exerted against the lever to operate the plates preparatory to dumping, the weight of the load on the hinged count of the inclination of the slats.

the end of the box and the slat for relieving the pressure or end thrust of the contents, which has a tendency to work forward on ac- When it is desired to dump only a portion of the contents of the box, the links are broken by hand, releasing the locking-knuckle between the points of connection with the shafts, as shown in Fig. 3, by means of which each slat or plate may be operated separately and the contents carried or supported upon each slat or plate are dumped. The links are broken by exerting a slight pressure in an upward direction under the lockingknuckle. The knuckles support and lock the links at the point of their connection between the crankshafts below the dead-center, thereby resisting the tendency of the links to break when it is desired to empty all of the contents of the box simultaneously.
